Cause:
The error message generally contains a line number. The point corresponding to that line does not meet the convergence condition for iterative inverse kinematics, triggering the error.
Troubleshooting:
Check the error message for other errors, such as a position limit violation. If there is a position limit violation, first check whether the point exceeds the limit and modify the point. If the error message contains no limit violation and only error 390, back up the system and submit a software defect report.
Solution:
Modify the point information.
Case sharing:
None.
